The Imperial Hammers Elite Armor Unit, nicknamed "Hell's Hammers," was an elite vanguard armor regiment within the Imperial Army that was stationed in Jedha City. It consisted of various stormtroopers, including tank troopers and tank trooper commanders. They made use of the TX-225 GAVw "Occupier" combat assault tanks. First Sergeant Jimmon Arbmab was one such member of this group, and he and his vehicle participated in the Jedha insurgency. The heavy infantry of the regiment were equipped with reciprocating quad blaster cannons, and the Rebel Alliance found it impossible to salvage the blaster cannons from the unit.
